A Slightly Different Morning Glory

Those varieties of sweet potato (Ipomoea batatas) that have become as popular as ornamental annuals over the last couple of years are largely grown for their foliage and do not seem to flower very often, but when they do it becomes really apparent that they are, in fact, morning glories:

I wonder if the tubers produced by these ornamental varieties are any good, or whether they are insipid or unpalatable like ornamental selections of some other food plants.

  1. Here, some ornamental sweet potatoes are also grown for their tuber too. But the tubers are not formed optimally. The common sweet potatoes usually will pruned and the stem that laying on the ground will be pull up in order to optimizing the tuber size on the main stem.

    1. Oh wow, thanks for that information! Makes sense to raise the shoots to direct all the energy to the main tubers since they root everywhere they touch the ground

  2. I think the tubers are edible and just as sweet, just not making a good crop per plant as far as I'm aware of.

    1. Interesting... When I tried growing one of the "regular" varieties the plants grew like crazy but also did not produce a lot of bulbs. The slips came from store-bought tubers, though, so maybe they just were not well adapted to local conditions.
